  • 250 GB capacity stores large desktop workloads

Dell 250GB 7.2K SAS 3G LFF Drive

This internal 3.5in hard drive delivers 250GB of storage at 7200RPM over a SATA 3Gb/s interface. It is suited for desktop workstations or legacy servers that require a direct-replacement Dell part with a 16MB cache buffer.

Thermals noise and power

The 7200RPM spindle speed produces typical mechanical drive acoustics and heat output for a 3.5in form factor. Power draw scales with the SATA 3Gb/s interface specification and the 2.0 pound mass indicates standard desktop drive construction.

Original Dell model and 16MB cache

The drive ships as an exact Dell part number match, ensuring firmware compatibility with supported Dell systems. The 16MB buffer helps sustain sequential throughput during routine read and write workloads.

Questions about this item

How do I install this 3.5" SATA 3Gb/s drive in a desktop, and what step do people often miss?

Mount the 3.5" LFF drive in a standard bay, connect the SATA data and power cables, then enable the SAS-compatible controller in BIOS so the 7200RPM drive is recognised.

What maintenance or replacement will this 250GB 7200RPM drive need later?

No routine maintenance is required; monitor SMART attributes and replace the drive if reallocated sectors appear or after the 1-year warranty period ends.

What limit appears first on this 16MB cache drive during sustained use?

The 3Gb/s SATA interface caps sustained throughput, so sequential transfers plateau at the interface speed before the 7200RPM platters become the bottleneck.
